Hoorn, C., Kukla, T., Bogotá-Angel, G., van Soelen, E., González-Arango, C., Wesselingh, F. P., … Morley, R. J. (2021). Cyclic sediment deposition by orbital forcing in the Miocene wetland of western Amazonia? New insights from a multidisciplinary approach. Global and Planetary Change, 103717. doi:10.1016/j.gloplacha.2021.103717 https://doi.org/10.1016/j.gloplacha.2021.103717

In the Miocene, a large wetland system extended from the Andean foothills into western Amazonia. This system has no modern analogue and the driving mechanisms are not yet fully understood. Dynamic topography and Andean uplift are thought to have controlled deposition, with allocyclic base level chan…

Vasconcelos, T., Boyko, J. D., & Beaulieu, J. M. (2021). Linking mode of seed dispersal and climatic niche evolution in flowering plants. Journal of Biogeography. doi:10.1111/jbi.14292 https://doi.org/10.1111/jbi.14292

Aim: Due to the sessile nature of flowering plants, movements to new geographical areas occur mainly during seed dispersal. Frugivores tend to be efficient dispersers because animals move within the boundaries of their preferable niches, so seeds are more likely to be transported to environments tha…

Xue, T., Gadagkar, S. R., Albright, T. P., Yang, X., Li, J., Xia, C., … Yu, S. (2021). Prioritizing conservation of biodiversity in an alpine region: Distribution pattern and conservation status of seed plants in the Qinghai-Tibetan Plateau. Global Ecology and Conservation, 32, e01885. doi:10.1016/j.gecco.2021.e01885 https://doi.org/10.1016/j.gecco.2021.e01885

The Qinghai-Tibetan Plateau (QTP) harbors abundant and diverse plant life owing to its high habitat heterogeneity. However, the distribution pattern of biodiversity hotspots and their conservation status remain unclear. Based on 148,283 high-resolution occurrence coordinates of 13,450 seed plants, w…

Schneider, K., Makowski, D., & van der Werf, W. (2021). Predicting hotspots for invasive species introduction in Europe. Environmental Research Letters. doi:10.1088/1748-9326/ac2f19 https://doi.org/10.1088/1748-9326/ac2f19

Plant pest invasions cost billions of Euros each year in Europe. Prediction of likely places of pest introduction could greatly help focus efforts on prevention and control and thus reduce societal costs of pest invasions. Here, we test whether generic data-driven risk maps of pest introduction, val…

Wang, C.-J., & Wan, J.-Z. (2021). Functional trait perspective on suitable habitat distribution of invasive plant species at a global scale. Perspectives in Ecology and Conservation. doi:10.1016/j.pecon.2021.07.002 https://doi.org/10.1016/j.pecon.2021.07.002

Plant invasion has been proved to threaten biodiversity conservation and ecosystem maintenance at a global scale. It is a challenge to project suitable habitat distributions of invasive plant species (IPS) for invasion risk assessment at large spatial scales. Interaction outcomes between native and …

Baumbach, L., Warren, D. L., Yousefpour, R., & Hanewinkel, M. (2021). Climate change may induce connectivity loss and mountaintop extinction in Central American forests. Communications Biology, 4(1). doi:10.1038/s42003-021-02359-9 https://doi.org/10.1038/s42003-021-02359-9

The tropical forests of Central America serve a pivotal role as biodiversity hotspots and provide ecosystem services securing human livelihood. However, climate change is expected to affect the species composition of forest ecosystems, lead to forest type transitions and trigger irrecoverable losses…

Gomides, S. C., Machado, T. M., Evangelista‐Vale, J. C., Martins‐Oliveira, A. T., Pires‐Oliveira, J. C., Muller, A., … Eisenlohr, P. V. (2021). Assessing species reintroduction sites based on future climate suitability for food resources. Conservation Biology. doi:10.1111/cobi.13796 https://doi.org/10.1111/cobi.13796

The reintroduction of a species that is extinct in the wild demands caution because reintroduction locations may be associated with threats, such as hunting, poor-quality habitat, and climate change. This is the case for Cyanopsitta spixii (Spix's Macaw), which has been extinct in the wild since 200…

Scherrer, D., Esperon‐Rodriguez, M., Beaumont, L. J., Barradas, V. L., & Guisan, A. (2021). National assessments of species vulnerability to climate change strongly depend on selected data sources. Diversity and Distributions. doi:10.1111/ddi.13275 https://doi.org/10.1111/ddi.13275

Aim: Correlative species distribution models (SDMs) are among the most frequently used tools for conservation planning under climate and land use changes. Conservation-focused climate change studies are often conducted on a national or local level and can use different sources of occurrence records …

Dellinger, A. S., Pérez‐Barrales, R., Michelangeli, F. A., Penneys, D. S., Fernández‐Fernández, D. M., & Schönenberger, J. (2021). Low bee visitation rates explain pollinator shifts to vertebrates in tropical mountains. New Phytologist. doi:10.1111/nph.17390 https://doi.org/10.1111/nph.17390

Evolutionary shifts from bee to vertebrate pollination are common in tropical mountains. Reduction in bee pollination efficiency under adverse montane weather conditions was proposed to drive these shifts. Although pollinator shifts are central for the evolution and diversification of angiosperms, w…

ALMEIDA, R. B. P., ANTAR, G. M., FERREIRA, A. W. C., SILVA JUNIOR, W. R. D., DE OLIVEIRA, M. S., & SARAIVA, R. V. C. (2021). Lectotypification and notes on the distribution of the giant herb Phenakospermum guyannense (Rich.) Miq. (Strelitziaceae). Phytotaxa, 491(3), 239–248. doi:10.11646/phytotaxa.491.3.4 https://doi.org/10.11646/phytotaxa.491.3.4

Phenakospermum guyannense is the only native species of Strelitziaceae in South America and occurs in the Amazon domain in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname and Venezuela. The species presents a negative sampling bias, probably due to the great effort necessar…
